Boss GE-10 EQ repair help needed

[KarateChamp]

I have a Boss GE-10 EQ that i love, but i was playing a wedding on a very hot summer day, i covered it up after soundcheck but when i came back for the show it had stopped working. Got around to opening it up today
And there is no visible damage to any of the components. Just wanted to check with you guys to what component is most likely to overheat in there, thanks in advance
